Description
I break the U(1)$_\text{EM}$ of the standard model by introducing new general scalar fields that obtain vacuum expectation values in their non-neutral components.
This is realised with either minicharged particles or with scalars that allow for new renormalisable interactions, which I will illustrate at the example of fermion-fermion-photon interactions.
Finally, I show how non-trivial behaviour can lead to strong limits by considering electron decay.
